Chief, I don't know if you use their glaze recipe, but back when I used to make doughnuts, I used one like that and it always made the doughnuts mushy if they didn't all get eaten right away. Leftovers didn't happen often but once in a while. My dad who lived in a small town with this wonderful doughnut shop was talking to the shop's owner once, who was not really a friend but sort of?, that I had made him doughnuts the last time he visited me but that my glaze made the doughnuts mushy after a bit. The guy told him to tell me to try using light Karo syrup instead of water for the liquid, plus the vanilla and powdered sugar. I guess you could also make your own by boiling sugar and water to a syrup too.

Katie H, if you see this, I don't know if Red's is even still open or if you guys eat doughnuts, but they were always so good. I used to bug my parents to stop and get doughnut holes if we were on that side of town when I was a kid. And I always had to make a visit there at least once when we want back home to visit.
